Frequency Response Study on the ERCOT under High Photovoltaic (PV) Penetration Conditions
Solar photovoltaic (PV) generation is growing rapidly around the world. However, PV generation, based on inverter, is fundamentally different from conventional synchronous generators. It is of vital importance to understand the impacts of increased penetration of PV generation on power system dynamic performance. This paper investigates frequency response of the Electric Reliability Council of Texas (ERCOT) with high PV penetration in the future year. In this work, a realistic baseline dynamic model is validated using synchrophasor measurements. Then, dynamic simulation is performed to evaluate the impacts of high PV generation on frequency response.
